The lens is made from a new plastic called Equalens II, which allows oxygen to diffuse freely across the lens into the eye. The cornea needs oxygen for the eye to function properly.
The new lens, which costs $2,500, rests on thesclera--the white part of the eye--and arches overthe cornea, creating a tiny gap.
Patients fill the lens--which is about the sizeof a quarter--with a lubricant, which in turnfills the space between the lens and the eye,providing lubrication to the irritated cornea andallowing the patient to see normally.
The new plastic was developed by the PolymerTechnology Corp. in Wilmington, Mass., whichworked together with Rosenthal's team indeveloping the lens.
Rosenthal founded Polymer Technology, and latersold it to Bausch & Lomb, Inc. He has been doingresearch on the lens since the 1970s
